as said in my other thread i bought a 383 in pieces that had busted a piston or 2 (crank is worth more than i paid for everything so well worth it) i ordered identical part #pistons to replace the 2 missing and 1 i wasn't comfortable using and the new ones have the coating on the skirts but the old ones dont I dont think this will cause any issues but has anyone else had anything like this happen

#2, according to thead for the pistons in jegs with 64cc heads i am looking at 10.9/1 compression with this high of a c.r. i amwanting to know would it be worth upgrading from the I-beam rods to a good set of h-beams

#3from what ive seen in my research i need around a 200cc intake runner on heads for this engine to breath adequately is that accurate and what heads have other fellow 383 fans had good luck with

thanks to all who read and thanks in general to everyone have found lots of good advice help and parts on this site not to mention inspiration for the project
